Materials provide interleaved practice opportunities with previously learned skills and concepts across learning pathways.
The Freckle adaptive pathway provides interleaved practice with previously learned skills and concepts across learning pathways. In each domain, students encounter problems that draw on multiple previously learned skills rather than practicing one skill in isolation. As the adaptive algorithm advances students through a domain, the algorithm introduces problems of increasing complexity that require applying and selecting among prior skills in combination. Students who perform well on one skill are not simply given more of the same type of problem. Instead, they are moved to content in which previously learned concepts intersect with new material, requiring them to integrate skills from across the learning pathway. Additionally, because the adaptive practice spans below-grade, on-grade, and above-grade content in the same domain, students regularly encounter problems that interleave earlier foundational skills with grade-level and above-grade-level applications.
The materials provide interleaved practice opportunities with previously learned skills and concepts by connecting number line instruction to students’ prior understanding of counting, numerical order, skip counting, place value, and measurement. For example, in the Add & Subtract 2-Digit Numbers Within 100 Nearpod lesson,
students apply previously learned skills to determine interval sizes, count forward and backward to identify missing values, and label points on number lines. The lesson also reinforces earlier concepts related to units, distance, and numerical relationships by asking students to create, interpret, and estimate locations on number lines. In addition, the materials connect learning across mathematical concepts and pathways by emphasizing that numbers represent both position and distance. Students draw on prior knowledge of measurement and counting to develop a deeper understanding of number magnitude, intervals, and estimation. The lesson further supports conceptual coherence by explicitly connecting number line representations to future learning involving measurement with rulers, meter sticks, and other measurement tools.
